Search for the Anomalous t q γ and t q H Couplings in γ p Collision at the LHC

Abstract EN

We have investigated the constraints on the anomalous t q γ and t q H ( q = u , c ) couplings through the photoproduction processes p p → p γ p → p t γ X → p b l + ν l γ X and p p → p γ p → p t H X → p b l + ν l b b - X at the LHC.

We have obtained 95% confidence level bounds on the anomalous couplings by considering various values of detector acceptances and integrated luminosities.

Improved constraints on the t q γ coupling have been obtained compared to current bounds.
